Abstract (en)
[origin: US4349582A] A method for coating the interior of electrically non-conductive pipes by means of a reactive separation from a gas flowing through the pipe, whereby the gas is dissociated by an electrical gas discharge, and wherein the separation occurs simultaneously throughout the total pipe length. Pulse discharges are used having pulse lengths which are so adjusted to the transit time of the gas through the pipe that the time period between two successive pulses corresponds to the time which is required for filling the pipe with unused gas.
